Abstract (en)
1. Process for the production of a polyamide macromer carrying at least two unsaturations, one of which is at each of the two ends of the polyamide sequence, characterised in that it consists in polymerizing the greater part of a polyamide monomer of at least 5 carbon atoms or heating a greater part of a polyamide oligomer in the presence of a minor part of at least one unsaturated compound likely to react with the terminal group(s) -NH2 and/or -COOH of the polyamide formed, as well as of a minor part of an auxiliary compound effecting the fixing of the unsaturated compound at both ends of the polyamide chain, the three reacting materials being held in the molten state at a temperature above that at which their final combination melts.
Abstract (fr)
Production d'un macromère polyamide portant au moins deux insaturations, dont une à chacune des deux extrémités de la séquence de polyamide : il consiste à polymériser une majeure partie d'un monomère de polyamide à au moins 5 atomes de carbone ou à chauffer une majeure partie d'un oligomère de polyamide en présence d'un partie mineure d'au moins un composé insaturé, susceptible de réagir avec le ou les groupes terminaux, - NH2 ou/et -COOH du polyamide formé, ainsi que d'une partie mineure d'un composé auxiliaire assurant la fixation du composé insaturé aux deux extrémités de la chaîne polyamide, les trois matières réagissantes étant maintenues à l'état fondu à une température supérieure à celle à laquelle fond leur combinaison finale.
